INSTALLATION

4) Light the pilot and turn the valve to "ON" position.

5) The pressure check should be carried out with

the unit burning and the setting should be within

the limits specifi ed on the safety label.

6) When

fi nished reading manometer, turn off the

gas valve, disconnect the hose and tighten the

screw (clockwise) with a 1/8" fl at screwdriver.

Screw should be snug, but do not over tighten.

GAS PIPE PRESSURE

TESTING

The appliance must be isolated from the gas

supply piping system by closing its individual

manual shut-off valve during any pressure

testing of the gas supply piping system at test

pressures equal to or less than 1/2 psig. (3.45

kPa). Disconnect piping from valve at pressures

over 1/2 psig (14" w.c.).

The manifold pressure is controlled by a regulator

built into the gas control, and should be checked

at the pressure test point.

Note: To properly check gas pressure,

both inlet and manifold pressures
should be checked using the valve
pressure ports on the valve.

1) Make sure the valve is in the "OFF" posi-

tion.

2) Loosen the "IN" (# 7) and/or "OUT" (# 6)

pressure tap(s), turning counterclockwise

with a 1/8" wide fl at screwdriver.

3) Attach manometer to "IN" and/or "OUT"

pressure tap(s) using a 5/16" ID hose.

GAS CONNECTION

The gas line can be rigid pipe, or to make instal-
lation easier, use a listed fl exible connector if
allowed by local codes. Copper may also be
used if approved by local codes.

The gas connection at the valve is 3/8" NPT.
For minimum and maximum supply pressure
see the System Data Table.
